Abstract
The effects of precipitation temperature on both structural and magnetic properties of polyethylene glycol-coated Mn0.8Zn0.2Fe2O4 nanoparticles are presented. Samples were prepared via co-precipitation method at different precipitation temperatures ranged 25–100 ∘C. X-ray diffraction analysis revealed that both crystallite size and lattice constant of the nanoparticles increased with increasing of temperature. FESEM images verified the existence of crystalline ferrites of diameter ranged 7.49–9.41 nm. FTIR spectra evidenced the effect of precipitation temperature on Fe 3+—O 2− stretching vibration in the ferrites. These Mn0.8Zn0.2Fe2O4 nanoparticles exhibited the highest saturation magnetization 20.938 emu/g at 75 ∘C. Correlations among precipitation temperature alteration, structural morphology, and magnetic response are established.
